BOTTLE-SEALING EAND STQPPER-RETAININQG DEVICE.

SPECIFICATION forming part of Letters Patent No. 521,752, dated June 19,1 894.

Application filed April 27,1894. SerialN0. 1 Nomodel T0 at whom it may concern:

I Be it known that I, NATHANIEL B. ABBOTT, a citizen of the United States, residing at Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in Bottle-Sealing and Stopper-Retaining Devices, of which the following is a specification.

My invention relates to the class of devices designed for closing bottles against internal gaseous pressure, such device usually comprising a sheet metal cap containing a disk of cork. These caps are usually made from tinplate, and the cap is applied over the mouth of a bottle having a groove about its neck or fillet near its mouth, tl1e pendent flange of the cap being then crimped under the shoulder formed by the groove. This crimping forms corrugations, the edge of the flange presenting projecting scallops. I

The object I have in view is to provide a cap of stiff, resilient sheetmetal, capable of g Fig.2 is a sideelevation of the retaining the stopper or seal against internal pressure, which sh all provide against leakage, and the flange of which shall fit closely to the bottle-neck all around andnot present projections at its margin, all as will be hereinafter described.

In the drawings which .serve to illustrate an'embodimentof my invention-Figure 1 is a transverse mid-section of the sealing cap. same, and Fig. 3 isa plan thereof. These views show the cap before itis applied. Fig. at is a side view of the neck-portion of a bottle formed especially to receive the cap, with a cap in place thereon. This view also shows the tool or implement for removing the cap. Fig. 5 is an under side view of the cap-removing im .plement. Fig. 6 is-a fragmentary sectional View of the cap on a large scale to show the lining more clearly than Fig. 1;"and Fig. 7 shows the form of the bottle-neck adapted to receive the cap.

or represents a cap, of sheet metal, preferably thin tin-plate. This cap islined throughout with paper, 1), represented in Fig. 1 by a heavy black line. This paper I apply to the blank of sheet, metal before it is cupped, by preference, and it will be, by preferenoe, a rather soft and relatively thick material.

Within the cap is a disk of cork, c. The neck, d, of the bottle to which the cap is to be applied flares toward the mouth of the bottle, so that when the cap-is placed thereon and the pendent flange of the cap rolled down upon the neck smoothly, the flange forms a retainer to hold the cap in place against internal'pressure.

In applying a cap made from stiff, refractory metal-such as is necessary to form a retainer against gaspressure from within-it is necessary to take up the surplus metal of the flange to some extent in closing the latter about the neck of the bottle, and as I desire to avoid corrugations and projections of the metal, and the bottle-neck has no recesses to receive the metal, I roll down the flange upon the bottle-neck with a steel roller or knurl having in it short projecting points which form numerous indentations, 6, (Fig.4) in the flange, the metal being forced into the softer packing paper b, forming thelining and cushion of the cap. The paper lining forms also a packing to guard against leakage which is liable to occur if either the cork disk or hot tle mouth should bedefective, or the disk should not be properly placed. Other soft cushioning and packing; material than paper might-be employed to line the cap, but paper is the cheapest and serves the purpose. The paper may be plain, or be saturated or coated with some waxysubstance. It.- will be noted that the paper lining is cupped in the same manner as the metal cap and with the latter so that the paper forms a smooth, adherent lining for the cap. The lining is interposed. between the disk of cork and the crown of the cap. I usually employ for the cupped lining the paper used by builders for sheathing houses. g

An implement, g, for removing the cap is clearly illustrated in Figs. 4. and 5. It is of steel and comprises a handle furnished with two hooks to take under the edge of the cap.

Fig. 4 shows the implement in position; by a downward pressure on the handle the cap is forced off at one side.
